JAMES B. MICHENER, OF KOKOMO, INDIANA.

GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 482,094, datedSeptember 6, 1892. Application filed February 13, 1892. Serial No.421,367. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JmuEs B. MICHENER, a citizen of the United States,residing at Kokomo, in the county of Howard and State of Indiana, haveinvented a new and useful Improvement in Gas-Stoves, of which thefollowing is a specification.

My invention relates to an improvementin heating-stoves which use gas asa fuel.

The objects of my improvement are to combine the advantages of radiationfrom a heated metallic surface and reliection from an open lire and togather the products of combustion and thoroughly utilize the heattherefrom. l

The accompanying drawings illustrate my invention.

Figure l represents a side elevation of the stove. Fig. 2 represents acentral vertical section. Fig. 3 represents a transverse section at a,Fig. 2.

In the drawings, A indicates a hollow bowlshaped structure having itswider end uppermost and open and its smaller end closed7 the bowl beingmade, preferably, of cast-iron and forming the body of the stove.

B is a hollow semispherical gas-chamber having at its lower side anopening to receive the gas-supply pipe C and having, also, initsinterior a central hub D, which is connected with the walls of thechamber by radial arms E. (See Fig. 3.) The lower end of bowl A issecured to the hub D of chamber B by a bolt F, the arrangement beingsuch that a narrow annular space Gris formed between the exterior of thebowl and the interior of the chamber B.

H is a hood or cover of considerably larger diameter than the open upperend of the bowl and provided on its interior or under side with lugs II, arranged at intervals so as to support said hood at a short distanceabove the upper edge of the bowl. Hood H is provided with a centralopening J, surrounded by a flange K, which is adapted to receive a pipeto convey away the products of combustion. Secured to the under side ofhood I-I, so as to form a downward extension of the opening J, is a pipeL.

The gas-supply pipe C forms a standard to support the stove at asuitable height above the floor and is provided with the usual gasjet Mand mixer N.

In operation gas being admitted to pipe C through the jet M isdischarged and ignited at the annular opening G, which surrounds thelower end of bowl A. The resulting flame completely surrounds andenvelopes the bowl, and the products of combustion, being intercepted bythe yradially and downwardly projecting edges of hood H, pass over theupper edge of the bowl and thence downward along its interiorsurface andare discharged through the pipe L and opening J. By this arrangement thebowl A and hood H become highly heated and heat the air by radiation,which elfect is supplemented by reflection from the open llamesurrounding the bowl.

I claim as my inventionl. In a stove, the combination of the hollowtapering bowl having its lower and smaller end closed, the opengas-chamber of larger diameter than the smaller end of the bowl andforming therewith an annular gas-j et surrounding the exterior of thebowl, the hood arranged to cover the open upper end of the bowl and toconduct the products of combustion to the interior thereof, said hoodbeing provided with an opening for the escape of the products ofcombustion,and a gas-supply pipe connected to said gas-chamber andarranged to form a support therefor, all substantially as set forth.

2. In a stove, the combination of the hollow tapering bowl having itslower` and smaller end closed, the open gas-chamber of larger diameterthan the smaller end of the bowl and forming therewith an annular gas-jet surrounding the exterior of the bowl, the hood arranged to cover theopen upper end of the bowl and to conduct the products of combustion tothe interior thereof, said hood being provided with an opening for theescape of the products of combustion, the pipe secured to said hoodbeneath said opening and forming an extension thereof downwardly intothe interior of the bowl, and a gas-supply pipe connected to saidgas-chamber, all arranged to co-operate,substantially as set forth,whereby the bowl is heated exteriorly by an open flame and interiorly by theescaping products of combustion.

3. As a new article of manufacture, a gasby the exterior of the bowl maybe surrounded stove consisting of a tapering bowl-shaped by an openflame and be heated interiorly by 1o body surrounded at its smaller endby an anthe products of combustion, substantially as nular gas-jet andprovided at its upper open set forth.

5 end with a hood arranged to gather the pro- JAMES B. MIOHENER.
